Benth., a wild relative of pigeonpea (Cajanus cajan (L.) Millsp.) ispublished: pub subjects: s1.2 full_text_status: restricted keywords: Atylosia scarabaeoides - Cajanus cajan - pigeonpea - variation abstract: Atylosia scarabaeoides (L.) Benth., a wild relative of pigeonpea, possesses several useful genes which can be utilized for pigeonpea improvement. In the present study, 33 accessions of A. scarabaeoides were evaluated at ICRISAT Center during the 1987 rainy season for variation in some useful traits to identify parents for inter-generic hybridization. A large variation was observed for leaf components, seed size, pod length, seeds/pod, days to flowering, seed protein, sulphur amino acids, resistance to cyst nematode, phytophthora blight, sterility mosaic, fusarium wilt, pod borer, pod fly, and pod wasp. Only four accessions were found to have more than 28% protein content. Methionine and cystine contents were marginally higher than in pigeonpea but the variation was not large enough to utilize them in the breeding program. In A. scarabaeoides. accessions resistant to fusarium wilt, phytophthora blight, sterility mosaic, and cyst nematode were detected. Compared to pigeonpea, the A. scarabaeoides accessions were less susceptible to lepidopteran borer and were immune to pod fly damage. Accessions ICPW 89 and ICPW 111 in short- (100–120 days), and ICPW 94 and ICPW 118 in medium-duration (140–180 days) were identified as potential parents for use in inter-generic hybridization date: 1990 date_type: published publication: Euphytica volume: 49 number: 3 publisher: Springer pagerange: 185-191 refereed: TRUE issn: 0014-2336 official_url: http://www.springerlink.com/content/nj3477r305374t06/ related_url_url: http://scholar.google.co.in/scholar?q=Intra+species+variation+in+Atylosia+scarabaeoides+%28L.%29+Benth.%2C+a+wild+relative+of+pigeonpea+%28Cajanus+cajan+%28L.%29+Millsp.%29+&hl=en&as_sdt=1%2C5&as_sdtp=on related_url_type: author citation: Saxena, K B and Singh, L and Reddy, M V and Singh, U and Lateef, S S and Sharma, S B and Remanandan, P (1990) Intra species variation in Atylosia scarabaeoides (L.)
